Returning directly whatever copy_to_user(...) or copy_from_user(...) returns may not do the right thing if there's a pagefault: copy_to_user/copy_from_user return the number of bytes not copied in this case, but ioctls need to return -EFAULT instead. Fix up kvm on mips to do return copy_to_user(...)) ? -EFAULT : 0; and return copy_from_user(...)) ? -EFAULT : 0; everywhere. Cc: stable@vger.kernel.org Signed-off-by: Michael S.
